Benefits of technology

[0008]Consistent with some embodiments, there is further provided a method for providing multicast addressing in an overlay network. The method includes steps of sending a packet from a first VM of a plurality of VMs on a host and receiving the packet at a virtual switch on the host in communication with the first VM. The packet includes a customer-specific multicast IP address of a mu

Problems solved by technology

Additionally, some data center customers may need very large numbers of virtual machines.
However, there are several issues with using that approach such as the number of tenants, the requirements for the network to support a large number of MAC ad

Embodiment Construction

[0019]In the following description specific details are set forth describing certain embodiments. It will be apparent, however, to one skilled in the art that the disclosed embodiments may be practiced without some or all of these specific details. The specific embodiments presented are meant to be illustrative, but not limiting. One skilled in the art may realize other material that, although not specifically described herein, is within the scope and spirit of this disclosure.

[0020]For purposes of this disclosure, an information handling system may include any instrumentality or aggregate of instrumentalities operable to compute, classify, process, transmit, receive, retrieve, originate, switch, store, display, manifest, detect, record, reproduce, handle, or utilize any form of information, intelligence, or data for business, scientific, control, or other purposes. For example, an information handling system may be a personal computer, a network storage device, or any other suitabl...

Abstract

An information handling system is provided. The information handling system includes a first hypervisor running on a first host and a second hypervisor running on a second host. The first hypervisor managing a first virtual switch, and the second hypervisor managing a second virtual switch. The information handling system also includes a plurality of virtual machines (VMs), including a first VM, which is part of a first tenant, running on the first host, and a second VM, part of a second tenant, running on the second host. The first virtual switch has a mapping in memory that maps a customer-specific multicast IP address, used by the plurality of VMs to indicate a multicast group that includes VMs on the first and second tenants, to a global multicast IP address used by the first and second hosts.

Description

BACKGROUND[0001]1. Technical Field[0002]The present disclosure is related to information handling systems. In particular, embodiments disclosed herein are related to multicast routing in a virtualized network environment.[0003]2. Discussion of Related Art[0004]As the value and use of information continues to increase, individuals and businesses seek additional ways to process and store information. One option available to users is information handling systems. An information handling system generally processes, compiles, stores, and / or communicates information or data for business, personal, or other purposes thereby allowing users to take advantage of the value of the information. Because technology and information handling needs and requirements vary between different users or applications, information handling systems may also vary regarding what information is handled, how the information is handled, how much information is processed, stored, or communicated, and how quickly and...
